1.Motion,move,movement refer to change of position in space. Motion denotes change of position, either considered apart from, or as a characteristic of, something that moves; usually the former, in which case it is often a somewhat technical or scientific term: perpetual motion. The chief uses of move are founded upon the idea of moving a piece, in chess or a similar game, for winning the game, and hence the word denotes any change of position, condition, or circumstances for the accomplishment of some end: a shrewd move to win votes.Movement is always connected with the person or thing moving, and is usually a definite or particular motion: the movements of a dance.3. bearing, carriage.
